Carolina Gardening: Vine ID anyone?

While I did post this on the Vine forum thought I'd ask you all what you thought as many of you live in woody areas like I do...found this blooming yesterday in a shady wooded area that gets filtered morning sun...Thanks!

Agree with imzadi, based on the color. C. ternatea is a much "bluer" blue, but the flower is about the same size and shape, and leaves appear identical (to me). A grower friend of mine fell in love with C. ternatea a few years ago and decided to propogate/sell them. There was virtually no interest from the retailers she supplied. As usual, she always listed the Botanical name first on the plant stakes in the pots. She couldn't understand why these beautiful plants she had grown generated zero interest in her customers. She had a sudden "Gestalt" moment, and instead of printing "Clitoria ternatea" on her labels the next year, she printed "Blue Heaven" (or some such silly descriptor), followed by "C. ternatea". Sold her entire crop in the first 3 weeks, and had to scramble to fill demand through the rest of the season... What's in a name? (Apparently, EVERYTHING!). True story.
